In 1950, in the Apostolic Constitution Munificentissimus Deus, Pope Pius XII proclaimed the Assumption of Mary a dogma of the Catholic Church in these words: "The Immaculate Mother of God, the ever-virgin Mary, having completed the course of her earthly life, was assumed body and soul into heaven." That belief was ancient, dating back to the apostles themselves. What was clear from the beginning was that there were no relics of Mary to be venerated, and that an empty tomb stood on the edge of Jerusalem near the site of her death. That location also soon became a place of pilgrimage. (Today, the Benedictine Abbey of the Dormition of Mary stands on the spot.)
